MILAN, Nov 2 (Reuters) - Italian new car sales fell for a second month in October, though at a slower pace, as a change towards tougher emissions tests kept weighing on the market.

New registrations fell 7.4 percent year on year to 146,655 vehicles, the transport ministry said on Friday.

The tougher new Worldwide Harmonised Light Vehicle Test Procedure (WLTP) became mandatory from the start of September, forcing some carmakers to clear inventory of older models in August via discounts.
